Siv thiab Synthesis ntawm Piperazine-N, N'-bis (2-hydroxypropanesulfonic acid) disodium ntsev
Daim ntawv thov: Piperazine-N, N-bis (2-hydroxyethanesulfonic acid) sodium ntsev muaj sulfonic acid pawg ntawm lub nplhaib piperazine, tshuaj thiab cov yam ntxwv ntawm cov qauv txiav txim siab piperazine-N, N-bis (2-hydroxyethanesulfonic acid) acid) sodium ntsev tag. dissociates nyob rau hauv dej, uas yog ntaus nqi rau nws osmotic tsav tsheb hauv paus ntsiab lus, uas yog pab tau kom muaj siab osmotic siab.Lub caij no, thaum piperazine-N, N-bis (2-hydroxyethanesulfonic acid) sodium ntsev yog siv los ua ib qho khoom siv rau pem hauv ntej osmotic Chemicalbook diassorb solute, tsawg heev rov qab solute diffusion tuaj yeem ua tiav tau muab nws qhov kev teeb tsa peb sab.Cov txiaj ntsig no qhia tau hais tias siv tau thiab kev ua tau zoo ntawm piperazine-N, N-bis (2-hydroxyethanesulfonic acid) sodium ntsev raws li lub hauv paus osmosis desalter.Tseem ceeb heev, piperazine-N, N-bis (2-hydroxyethanesulfonic acid) sodium ntsev nyiam solutes thaum tsim cov dej osmotic siab rau pem hauv ntej nrog negligible reverse solute diffusion, validating lawv siv thiab muaj peev xwm.
Kev npaj: Piperazine-N, N-bis (2-hydroxyethanesulfonic acid) sodium ntsev (P-2SO3-2Na) tau npaj raws li hauv qab no: Piperazine (2.15 g, 25 mmol) tau yaj hauv 20 mL ntawm DI dej.Tom qab ntawd ClCH2CH2SO3Na (9.23 g, 50 mmol) thiab NaOH Chemicalbook (1.60 g, 50 mmol) tau ntxiv ua ntu zus.Cov kev daws teeb meem tau txuas mus ntxiv ntawm 40 ° C thaum hmo ntuj.Ib qho kev daws teeb meem meej tau tsim.Cov khoom tau txais los ntawm nag lossis daus los ntawm txias ethanol thiab purified los ntawm H2O / EtOH.Cov hmoov dawb piperazine-N, N-bis (2-hydroxyethanesulfonic acid) sodium ntsev tau sau tom qab ziab (> 99% tawm los).
